Answer:
Carbon makes up the majority of a tree's bulk. The carbon originates from the photosynthesis of carbon dioxide. Plants transform the sun's energy into chemical energy, which is trapped inside the bonds of carbon molecules formed from atmospheric carbon dioxide and water during photosynthesis. Yes, carbon dioxide from the air we breathe ends up in "food" molecules (called glucose), each of which includes six carbon atoms (and 12 hydrogen atoms and 6 oxygen atoms). There is, however, a downside to this. Plants utilise the energy contained in part of the carbon molecules they create to keep themselves alive and proliferate.Explanation:
35 grasshoppers/10 square meters has the highest population density.
- The highest population density of grasshoppers is 35 grasshoppers/10 square meters because more number of organisms are present in less area as compared to other population density.
- In the option i.e. 40 grasshoppers/20 square meters and 50 grasshoppers/30 square meters have more number of organisms but the area is also greater.
- And we know that high population density means more number of organisms in less area so we can conclude that 35 grasshoppers/10 square meters has the highest population density.

The question is incomplete, however, the statements associated with this question is given in the comments and here as well:
Neither facilitated diffusion nor osmosis requires cell energy.
Diffusion of gases and other small molecules requires no energy on the part of the cell.
Active transport requires cell energy and osmosis doesn't.
Both endocytosis and active transport require cell energy.
Answer:
The correct answer is - Active transport requires cell energy and osmosis doesn't.
Explanation:
Osmosis is an example of passive transport as it does not require energy to facilitate the movement of solvent In the process of osmosis,. It moves from high concentration to low concentration through the semipermeable membrane which is along the gradient so no requirement of energy.
In the case of Active transport, it requires energy to facilitate the movement of transport as it is the movement of a substance from low concentration to a high concentration area that is against the concentration gradient.
The leading cause is garbage and waste from people.
The correct answer is c. Genetic Variation. Bacteria are very numerous, ad random mutation of bacterial DNA generates a wide variety of change, including resistance.
